You could try installing it from Koji (koji DOT fedoraproject DOT org). Be aware that you will have to manually resolve dependency issues, which could be a bit cumbersome.

To know which dependencies are required, try installing the .rpm file that you downloaded, and it will give you an error with the list of dependencies. You will have to make a note of them. Then try installing them from koji or elsewhere. Upon trial and error, you will see that the dependencies have to be installed in a particular order. Some may even have to be compiled from source.
